Expand description

Trait over directional types

This trait has a variable implementation, Direction, and several fixed implementations, Right, Down, Left and Up.

Using a generic <D: Directional> allows compile-time substitution of direction information when parametrised with fixed implementations.

Associated Types

Direction flipped over diagonal (i.e. Down ↔ Right)

This allows compile-time selection of the flipped direction.

Direction reversed along axis (i.e. Left ↔ Right)

This allows compile-time selection of the reversed direction.

Required methods

Flip over diagonal (i.e. Down ↔ Right)

Reverse along axis (i.e. Left ↔ Right)

Convert to the Direction enum

Provided methods

Up or Down

Left or Right

Left or Up
